为减少工程机械液压系统噪声,必须对噪声源进行实际调查,掌握噪声源的频率大小及特性,并采取相应解决措施。本文通过论述液压系统结构改进以及对液压泵、液压阀等液压零部件产生的噪声分析,探讨降低液压系统噪声的有效途径。1.改进液压系统结构改进液压系统结构以降低噪声的方法有4种:一是选用低噪声液压元件代替高噪声液压元件。如用叶片泵
In order to reduce the noise of the hydraulic system of construction machinery, the noise source must be actually investigated, the frequency and size of the noise source must be mastered, and corresponding measures should be taken. In this paper, by discussing the structural improvement of hydraulic system and the noise analysis of hydraulic components such as hydraulic pump and hydraulic valve, the effective ways to reduce the noise of hydraulic system are discussed. 1. Improve the hydraulic system structure Improve the hydraulic system structure to reduce noise, there are 4 ways: First, the choice of low-noise hydraulic components instead of high-noise hydraulic components. Such as vane pump
